Now, remember that pelvic bone I was talking about?

The sciatic nerve then passes beneath the piriformis muscle, and through the greater sciatic foramen, which is an opening formed by the pelvic bone, sacrospinous and sacrotuberous ligaments.

And it had a pelvic bone, called the pubis, that pointed forward instead of backward, as it does in birds.

For example, the brain is protected by the cranial bones, the spinal cord by the vertebrae, the heart and lungs by the rib cage, and internal reproductive organs by the pelvic bones.

例如，大脑受到颅骨保护，脊髓被椎骨保护，心脏和肺被胸廓保护，内部的生殖器官由髋骨保护。
